ampere: wire internal microphone (MIC1) routing

Add coolpi-cm5-genbook DTS patch that mirrors vendor coolpi-kernel audio routing for the internal microphone: routing = "MIC1", "Main Mic", "MIC2", "Headset Mic"; Necessary-but-not-sufficient: the ES8316 RX aif_out widget power-up chain is still broken on mainline (separate issue, not addressed here); a future codec/audio-graph-card driver fix can complete the capture path once the topology is correct. Include in ampere fleet manifest.

+Subject: [PATCH] arm64: dts: rockchip: rk3588-coolpi-cm5-genbook: wire
+ internal microphone
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The CoolPi CM5 GenBook has an internal microphone wired to the ES8316
+codec MIC1 input. The upstream DTS only declared Mic Jack on MIC2
+(headset jack), so the DAPM graph has no path between MIC1 and a
+named widget — internal mic capture cannot work regardless of mixer
+settings.
+
+Vendor coolpi-kernel reference (rk3588-cpcm5-genbook.dts):
+	rockchip,audio-routing =
+		"MIC1", "Main Mic",
+		"MIC2", "Headset Mic";
+
+Mirror in the upstream audio-graph-card binding:
+  - widgets: split Mic Jack into Main Mic (internal) + Headset Mic
+    (external) so each input is addressable from ALSA UCM
+  - routing: MIC1 <- Main Mic, MIC2 <- Headset Mic
+
+This patch is necessary but not sufficient for working internal mic
+capture: a separate issue prevents the ES8316 RX aif_out widget from
+powering up via DAPM when arecord opens the capture PCM (I2S OUT stays
+inactive, bias_level stays Off). That second issue is not addressed
+here — this patch only fixes the static DTS topology so a future codec
+or audio-graph-card driver fix can complete the chain.
